convenient interface for
reading and writing text.</p>
<p>QTextStream can operate on a <a href="qiodevice.html">QIODevice</a>, a <a href="qbytearray.html">QByteArray</a> or a <a href="qstring.html">QString</a>. Using QTextStream's streaming
operators, you can conveniently read and write words, lines and
numbers. For generating text, QTextStream supports formatting
options for field padding and alignment, and formatting of numbers.
Example:</p>
<pre class="cpp">
 <span class="type"><a href="qfile.html">QFile</a></span> data(<span class="string">"output.txt"</span>);
 <span class="keyword">if</span> (data<span class="operator">.</span>open(<span class="type"><a href="qfile.html">QFile</a></span><span class="operator">.</span>WriteOnly <span class="operator">|</span> <span class="type"><a href="qfile.html">QFile</a></span><span class="operator">.</span>Truncate)) {
     <span class="type">QTextStream</span> out(<span class="operator">&amp;</span>data);
     out <span class="operator">&lt;</span><span class="operator">&lt;</span> <span class="string">"Result: "</span> <span class="operator">&lt;</span><span class="operator">&lt;</span> <a href="qtcore.html#qSetFieldWidth">qSetFieldWidth</a>(<span class="number">10</span>) <span class="operator">&lt;</span><span class="operator">&lt;</span> left <span class="operator">&lt;</span><span class="operator">&lt;</span> <span class="number">3.14</span> <span class="operator">&lt;</span><span class="operator">&lt;</span> <span class="number">2.7</span>;
     <span class="comment">// writes "Result: 3.14      2.7       "</span>
 }
</pre>
<p>It's also common to use QTextStream to read console input and
write console output. QTextStream is locale aware, and will
automatically decode standard input using the correct codec.
Example:</p>
<pre class="cpp">
 <span class="type">QTextStream</span> stream(stdin);
 <span class="type"><a href="qstring.html">QString</a></span> line;
 <span class="keyword">do</span> {
     line <span class="operator">=</span> stream<span class="operator">.</span>readLine();
 } <span class="keyword">while</span> (<span class="operator">!</span>line<span class="operator">.</span>isNull());
</pre>
<p>Besides using QTextStream's constructors, you can also set the
device or string QTextStream operates on by calling <a href="qtextstream.html#setDevice">setDevice</a>() or <a href="qtextstream.html#setString">setString</a>(). You can seek to a
position by calling <a href="qtextstream.html#seek">seek</a>(), and
<a href="qtextstream.html#atEnd">atEnd</a>() will return true when
there is no data left to be read. If you call <a href="qtcore.html#flush">flush</a>(), QTextStream will empty all
data from its write buffer into the device and call <a href="qtcore.html#flush">flush</a>() on the device.</p>
<p>Internally, QTextStream uses a Unicode based buffer, and
<a href="qtextcodec.html">QTextCodec</a> is used by QTextStream to
automatically support different character sets. By default,
<a href="qtextcodec.html#codecForLocale">QTextCodec.codecForLocale</a>()
is used for reading and writing, but you can also set the codec by
calling <a href="qtextstream.html#setCodec">setCodec</a>().
Automatic Unicode detection is also supported. When this feature is
enabled (the default behavior), QTextStream will detect the UTF-16
or the UTF-32 BOM (Byte Order Mark) and switch to the appropriate
UTF codec when reading. QTextStream does not write a BOM by
default, but you can enable this by calling
setGenerateByteOrderMark(true). When QTextStream operates on a
<a href="qstring.html">QString</a> directly, the codec is
disabled.</p>
<p>There are three general ways to use QTextStream when reading
text files:</p>
<ul>
<li>Chunk by chunk, by calling <a href="qtextstream.html#readLine">readLine</a>() or <a href="qtextstream.html#readAll">readAll</a>().</li>
<li>Word by word. QTextStream supports streaming into QStrings,
QByteArrays and char* buffers. Words are delimited by space, and
leading white space is automatically skipped.</li>
<li>Character by character, by streaming into <a href="qchar.html">QChar</a> or char types. This method is often used for
convenient input handling when parsing files, independent of
character encoding and end-of-line semantics. To skip white space,
call <a href="qtextstream.html#skipWhiteSpace">skipWhiteSpace</a>().</li>
</ul>
<p>Since the text stream uses a buffer, you should not read from
the stream using the implementation of a superclass. For instance,
if you have a <a href="qfile.html">QFile</a> and read from it
directly using <a href="qiodevice.html#readLine">QFile.readLine</a>() instead of using
the stream, the text stream's internal position will be out of sync
with the file's position.</p>
<p>By default, when reading numbers from a stream of text,
QTextStream will automatically detect the number's base
representation. For example, if the number starts with "0x", it is
assumed to be in hexadecimal form. If it starts with the digits
1-9, it is assumed to be in decimal form, and so on. You can set
the integer base, thereby disabling the automatic detection, by
calling <a href="qtextstream.html#setIntegerBase">setIntegerBase</a>().
Example:</p>
<pre class="cpp">
 <span class="type">QTextStream</span> in(<span class="string">"0x50 0x20"</span>);
 <span class="type">int</span> firstNumber<span class="operator">,</span> secondNumber;

 in <span class="operator">&gt;</span><span class="operator">&gt;</span> firstNumber;             <span class="comment">// firstNumber == 80</span>
 in <span class="operator">&gt;</span><span class="operator">&gt;</span> dec <span class="operator">&gt;</span><span class="operator">&gt;</span> secondNumber;     <span class="comment">// secondNumber == 0</span>

 <span class="type">char</span> ch;
 in <span class="operator">&gt;</span><span class="operator">&gt;</span> ch;                      <span class="comment">// ch == 'x'</span>
</pre>
<p>QTextStream supports many formatting options for generating
text. You can set the field width and pad character by calling
<a href="qtextstream.html#setFieldWidth">setFieldWidth</a>() and
<a href="qtextstream.html#setPadChar">setPadChar</a>(). Use
<a href="qtextstream.html#setFieldAlignment">setFieldAlignment</a>()
to set the alignment within each field. For real numbers, call
<a href="qtextstream.html#setRealNumberNotation">setRealNumberNotation</a>()
and <a href="qtextstream.html#setRealNumberPrecision">setRealNumberPrecision</a>()
to set the notation (<a href="qtextstream.html#RealNumberNotation-enum">SmartNotation</a>,
<a href="qtextstream.html#RealNumberNotation-enum">ScientificNotation</a>,
<a href="qtextstream.html#RealNumberNotation-enum">FixedNotation</a>) and
precision in digits of the generated number. Some extra number
formatting options are also available through <a href="qtextstream.html#setNumberFlags">setNumberFlags</a>().</p>

<p>Like <tt>&lt;iostream&gt;</tt> in the standard C++ library,
QTextStream also defines several global manipulator functions:</p>

<a href="qtextstream.html">QTextStream</a>; otherwise returns
false. This is similar to, but not the same as calling <a href="qiodevice.html#atEnd">QIODevice.atEnd</a>(), as <a href="qtextstream.html">QTextStream</a> also takes into account its

<h3 class="fn"><a name="pos" />int QTextStream.pos (<i>self</i>)</h3><p>Returns the device position corresponding to the current
position of the stream, or -1 if an error occurs (e.g., if there is
no device or string, or if there's a device error).</p>
<p>Because <a href="qtextstream.html">QTextStream</a> is buffered,
this function may have to seek the device to reconstruct a valid
device position. This operation can be expensive, so you may want
to avoid calling this function in a tight loop.</p>
<p>This function was introduced in Qt 4.2.</p>
<p><b>See also</b> <a href="qtextstream.html#seek">seek</a>().</p>


<h3 class="fn"><a name="read" />QString QTextStream.read (<i>self</i>, int&#160;<i>maxlen</i>)</h3><p>Reads at most <i>maxlen</i> characters from the stream, and

<h3 class="fn"><a name="readAll" />QString QTextStream.readAll (<i>self</i>)</h3><p>Reads the entire content of the stream, and returns it as a
<a href="qstring.html">QString</a>. Avoid this function when
working on large files, as it will consume a significant amount of
memory.</p>
<p>Calling <a href="qtextstream.html#readLine">readLine</a>() is
better if you do not know how much data is available.</p>
<p><b>See also</b> <a href="qtextstream.html#readLine">readLine</a>().</p>


<h3 class="fn"><a name="readLine" />QString QTextStream.readLine (<i>self</i>, int&#160;<i>maxLength</i>&#160;=&#160;0)</h3><p>Reads one line of text from the stream, and returns it as a
<a href="qstring.html">QString</a>. The maximum allowed line length
is set to <i>maxlen</i>. If the stream contains lines longer than
this, then the lines will be split after <i>maxlen</i> characters
and returned in parts.</p>
<p>If <i>maxlen</i> is 0, the lines can be of any length. A common
value for <i>maxlen</i> is 75.</p>
<p>The returned line has no trailing end-of-line characters ("\n"
or "\r\n"), so calling <a href="qstring.html#trimmed">QString.trimmed</a>() is unnecessary.</p>
<p>If the stream has read to the end of the file, readLine() will
return a null <a href="qstring.html">QString</a>. For strings, or
for devices that support it, you can explicitly test for the end of
the stream using <a href="qtextstream.html#atEnd">atEnd</a>().</p>

<h3 class="fn"><a name="reset" />QTextStream.reset (<i>self</i>)</h3><p>Resets <a href="qtextstream.html">QTextStream</a>'s formatting
options, bringing it back to its original constructed state. The
device, string and any buffered data is left untouched.</p>


<h3 class="fn"><a name="resetStatus" />QTextStream.resetStatus (<i>self</i>)</h3><p>Resets the status of the text stream.</p>
<p>This function was introduced in Qt 4.1.</p>

success; otherwise returns false.</p>


<h3 class="fn"><a name="setAutoDetectUnicode" />QTextStream.setAutoDetectUnicode (<i>self</i>, bool&#160;<i>enabled</i>)</h3><p>If <i>enabled</i> is true, <a href="qtextstream.html">QTextStream</a> will attempt to detect Unicode
encoding by peeking into the stream data to see if it can find the
UTF-16 or UTF-32 BOM (Byte Order Mark). If this mark is found,
<a href="qtextstream.html">QTextStream</a> will replace the current
codec with the UTF codec.</p>
<p>This function can be used together with <a href="qtextstream.html#setCodec">setCodec</a>(). It is common to set the
codec to UTF-8, and then enable UTF-16 detection.</p>
<p><b>See also</b> <a href="qtextstream.html#autoDetectUnicode">autoDetectUnicode</a>() and
<a href="qtextstream.html#setCodec">setCodec</a>().</p>


<h3 class="fn"><a name="setCodec" />QTextStream.setCodec (<i>self</i>, <a href="qtextcodec.html">QTextCodec</a>&#160;<i>codec</i>)</h3><p>Sets the codec for this stream to <i>codec</i>. The codec is
used for decoding any data that is read from the assigned device,
and for encoding any data that is written. By default, <a href="qtextcodec.html#codecForLocale">QTextCodec.codecForLocale</a>()
is used, and automatic unicode detection is enabled.</p>
<p>If <a href="qtextstream.html">QTextStream</a> operates on a
string, this function does nothing.</p>
<p><b>Warning:</b> If you call this function while the text stream
is reading from an open sequential socket, the internal buffer may
still contain text decoded using the old codec.</p>

<a href="qtextstream.html#setAutoDetectUnicode">setAutoDetectUnicode</a>(),
and <a href="qtextstream.html#setLocale">setLocale</a>().</p>


<h3 class="fn"><a name="setCodec-2" />QTextStream.setCodec (<i>self</i>, str&#160;<i>codecName</i>)</h3><p>Sets the codec for this stream to the <a href="qtextcodec.html">QTextCodec</a> for the encoding specified by
<i>codecName</i>. Common values for <tt>codecName</tt> include "ISO
8859-1", "UTF-8", and "UTF-16". If the encoding isn't recognized,
nothing happens.</p>
<p>Example:</p>
<pre class="cpp">
 <span class="type"><a href="qtextstream.html">QTextStream</a></span> out(<span class="operator">&amp;</span>file);

<h3 class="fn"><a name="setDevice" />QTextStream.setDevice (<i>self</i>, <a href="qiodevice.html">QIODevice</a>&#160;<i>device</i>)</h3><p>Sets the current device to <i>device</i>. If a device has
already been assigned, <a href="qtextstream.html">QTextStream</a>
will call <a href="qtcore.html#flush">flush</a>() before the
old device is replaced.</p>
<p><b>Note:</b> This function resets locale to the default locale
('C') and codec to the default codec, <a href="qtextcodec.html#codecForLocale">QTextCodec.codecForLocale</a>().</p>

<h3 class="fn"><a name="setFieldAlignment" />QTextStream.setFieldAlignment (<i>self</i>, <a href="qtextstream.html#FieldAlignment-enum">FieldAlignment</a>&#160;<i>alignment</i>)</h3><p>Sets the field alignment to <i>mode</i>. When used together with
<a href="qtextstream.html#setFieldWidth">setFieldWidth</a>(), this
function allows you to generate formatted output with text aligned
to the left, to the right or center aligned.</p>
<p><b>See also</b> <a href="qtextstream.html#fieldAlignment">fieldAlignment</a>() and <a href="qtextstream.html#setFieldWidth">setFieldWidth</a>().</p>


<h3 class="fn"><a name="setFieldWidth" />QTextStream.setFieldWidth (<i>self</i>, int&#160;<i>width</i>)</h3><p>Sets the current field width to <i>width</i>. If <i>width</i> is
0 (the default), the field width is equal to the length of the
generated text.</p>
<p><b>Note:</b> The field width applies to every element appended
to this stream after this function has been called (e.g., it also
pads endl). This behavior is different from similar classes in the
STL, where the field width only applies to the next element.</p>
<p><b>See also</b> <a href="qtextstream.html#fieldWidth">fieldWidth</a>() and <a href="qtextstream.html#setPadChar">setPadChar</a>().</p>


<h3 class="fn"><a name="setGenerateByteOrderMark" />QTextStream.setGenerateByteOrderMark (<i>self</i>, bool&#160;<i>generate</i>)</h3><p>If <i>generate</i> is true and a UTF codec is used, <a href="qtextstream.html">QTextStream</a> will insert the BOM (Byte Order
Mark) before any data has been written to the device. If
<i>generate</i> is false, no BOM will be inserted. This function

and <a href="qtcore.html#bom">bom</a>().</p>


<h3 class="fn"><a name="setIntegerBase" />QTextStream.setIntegerBase (<i>self</i>, int&#160;<i>base</i>)</h3><p>Sets the base of integers to <i>base</i>, both for reading and
for generating numbers. <i>base</i> can be either 2 (binary), 8
(octal), 10 (decimal) or 16 (hexadecimal). If <i>base</i> is 0,
<a href="qtextstream.html">QTextStream</a> will attempt to detect
the base by inspecting the data on the stream. When generating
numbers, <a href="qtextstream.html">QTextStream</a> assumes base is
10 unless the base has been set explicitly.</p>

<h3 class="fn"><a name="setLocale" />QTextStream.setLocale (<i>self</i>, <a href="qlocale.html">QLocale</a>&#160;<i>locale</i>)</h3><p>Sets the locale for this stream to <i>locale</i>. The specified
locale is used for conversions between numbers and their string
representations.</p>
<p>The default locale is C and it is a special case - the thousands
group separator is not used for backward compatibility reasons.</p>

<h3 class="fn"><a name="setNumberFlags" />QTextStream.setNumberFlags (<i>self</i>, <a href="qtextstream-numberflags.html">NumberFlags</a>&#160;<i>flags</i>)</h3><p>Sets the current number flags to <i>flags</i>. <i>flags</i> is a
set of flags from the <a href="qtextstream.html#NumberFlag-enum">NumberFlag</a> enum, and
describes options for formatting generated code (e.g., whether or
not to always write the base or sign of a number).</p>

<h3 class="fn"><a name="setPadChar" />QTextStream.setPadChar (<i>self</i>, QChar&#160;<i>ch</i>)</h3><p>Sets the pad character to <i>ch</i>. The default value is the
ASCII space character (' '), or <a href="qchar.html">QChar</a>(0x20). This character is used to fill in the
space in fields when generating text.</p>
<p>Example:</p>
